You mean this broscience chart floating around? Pot growers are some of the most gullible and misinformed of any group of growers.

That's great, I've never seen this chart before. I'll check if my seeds 'thump-thump' when I roll them like a tire :lol:, it's 100% accurate!

In all seriousness though, it's sounding like most of this crap I have read about controlling the sex is total bro science. Thanks for the input everyone!

Mechanisms Governing Biased Primary Sex Ratios.
In species with genetic sex determination, Mendelian inheritance should produce primary sex ratios of 1:1. However, both genetic and environmental factors can potentially modify the sex ratio of seeds, although the mechanisms involved are poorly understood (9). In theory, genes modifying primary sex ratios could alter the quantity or quality of female- versus male-determining pollen, or females could selectively abort seeds based on their gender. As yet, there is little evidence to support either mechanism

However sex is assigned to a seed before it's dropped by the plant. I have had strains like Strawberry Loctite that pop majority female. But the closer to the landrace you get the more even the split. From a few experiences.

Ok play nice plz, i sort of agree. I think the dense populations sense "hey we need more males or we're in trouble" so the hormones signal chromosome males at seed creation, like harley mentioned. When they're all alone in tents they dont have those environmental pressures so reverts to 1:1 life sustaining mean avg....i think

Let your regular seed plants grow around a bunch of females? I don’t know but I had like 12 fem seeds that I popped along with 6 regular seeds. Only ended up with 2 males ‍♂

t's really hard to sift through the mountain of bro science to find any solid information.
Reply with your techniques and/or thoughts! Thanks

If you don't want bro science then don't ask a forum full of bros. If you search for real science you'll find karyotypes and more that establish that Cannabis uses the XY sex determination system, just like humans and most sexual organisms.

The "you need males to breed" is more bro science! Ask them why and you will never get anything more specific than "it's missing the male genetics" or some other horseshit because it's just something made up by ignorant growers. It's the same nonsense from the same bros as "fems cause hermies!" except that the bros mostly gave up on that one after a million growers have used fems without issue.

Use females, your breeding program will be so much better when you can directly observe the female flower traits carried by both parents.

You're much better using the open source project called "openPCR" to conduct DNA testing to find the gender of the cannabis plant as soon as it produces 4 leaves after germination.
